ROBERT o. OHOPE, OF sYRAoUsE, NEW YORK.

RAILROAD-GATE.

SPECIFICATION forming part of Letters Patent No. 333,829, dated January5, 1886.

Application filed August 7. 1885.

To all whom, it may concern:

Be it known that I, ROBERT C. CHOPE, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Railroad- Gates, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the class of gates in which a cable or chainis extended horizontally across the road, and supported by another cableor chain connected with the central portion of said horizontal cable orchain, and extended over a pulley on the upper end of a post, and havingconnected to its pendent free end a counter-weight, which produces therequisite tension on the said supporting cable or chain.

The object of my invention is to dispense with the aforesaidcounter-weight and facilitate the operation of the gate; and to that endmy invention consists in the novel construction and combination ofparts,hereinafter fully described, and specifically set forth in theclaim.

In the annexed drawings, Figure I is a front elevation of my improvedgate, with some portions broken away to better illustrate some of thedetails; and Fig. II is a vertical section on line x x, Fig. I, withportions broken away for the purpose before stated.

Similar letters of reference indicate corresponding parts.

E and E represent two standards erected at opposite sides of the highwayor street to be guarded.

D D are the bars pivoted on said standards to swing in a vertical plane.Said bars are overbalanced by a weighted extension, D', back of thefulcrurn, so as to carry them automatically to an erect position, asrepresented in the drawings. They are thrown into a horizontal positionby means of a cable or chain, B, attached at one end to the foot of oneof the standards E, and extending thence over a pulley, a, on the freeend of the bar D, which is pivoted on said standard, thence across theroad to a pulley, a, on the free end of the other bar D, thence toapulley, b, on the foot of the standard E, to which the latter bar SerialNo. 173,810. (No model.)

is pivoted, and thence to a drum or winch, C, pivoted on said standard,upon which drum the said cable or chain is wound. In many cases the barsD D reach only part way across the road, and the cable or chain Bcompletes the barrier between the ends ofthe bars when drawn down into ahorizontal position, the bars being, however, of sufficient length tocarry the cable or chain B a proper elevation above the road for thepassage of vehicles carrying high loads, when the bars are raised intotheir vertical position, as represented in the drawings. The centralportion of this barrier cable or chain B is supported by posts I P,erected at opposite sides ofthe highway, and reaching above the bars D Dwhen in a vertical position. A stiff rod, 1', is extended from the topof one to the top of the other of said posts, and from the centralportion of this rod are suspended the pulleys c c, over which run thetwo branches ofthe chain or cable A, the extremities of said branchesbeing connected with the horizontal portion of the cable or chain B, andthe cable or chain A being extended Over a pulley, d, pivoted on theupper end of the post P, adjacent to the standard E', as shown in Fig. Iof the drawings. From the pulley d the cable or chain A is extended to apulley, b', pivoted to the lower portion of the standard E', and thenceto the drum or winch C, on which it is wound in opposite direction fromthe cable or chain B. In turning the drum or winch G in one directionthe cable or chain B is wound up, and thereby caused to draw down thebars D D to close the gate, as represented by dotted lines in Fig. I ofthe drawings. Simultaneously with this action the cable or chain A isunwound from the drum with the requisite velocity, and thus the pendentportions of the branches thereof are lowered to conform to thedescending barrier cable or chain B.

The described cables or chains B and A, when properly adj usted to therequisite tension, will operate perfectly in unison with each other,and, if desired, said cables or chains may consist of one continuouspiece.

It will be observed thatby myimprovements the weight heretofore employedfor drawing up the supporting cable or chain A is dis- IOO pensed with,and therefore the operation of In testimony whereof Ihave hereuntosigned the gate is facilitated. my name and affixed my seal, in thepresence Having described myinvention,whatlelaim of two attestingwitnesses, at Syracuse, in the 15 as new, and desire to secure byLetters Patent, county of Onondaga, in the State of New York, 5 1s- TheCombination, with the vertically-swinging gate-bars D D, drum C,bar-operating ea- ROBERT C.
